Sullinger pleaded not guilty to charges of domestic violence, malicious destruction of property and intimidation of a witness. He was released Tuesday on $5,000 bail.

The prosecution claims Sullinger pushed his girlfriend twice during an argument, grabbed the phone and blocked her from leaving their home.

According to court documents, the argument began when Sullinger's girlfriend, Deann Smith, claimed to find evidence of infidelity on his cellphone.

"During this heated argument in the bedroom, Jared pushed her down onto the bed and got on top of her," Waltham police wrote in a report. "Deann states she tried several times to get up, but he kept pinning her down and would not let her up."

"I voluntarily reported to the Waltham police this morning to respond to charges against me. The experience was humbling and embarrassing for me," Sullinger said in a statement.

Sullinger's girlfriend told the judge that she did not fear her boyfriend and said she did not need a stay-away order. But the judge disagreed, saying the couple can only be in contact via phone or in the presence of a third party.

“The Celtics were disappointed to learn of the allegations against Jared and are currently gathering more information on the situation, which we are taking very seriously," the team said in a statement.

Sullinger was a first-round draft pick for the Celtics in 2012.

Last season, rookie Sullinger averaged 6 points and almost 6 rebounds per game in 45 games.
